You need to configure the NGBundlePath default which is used to lookup OGo components.
On Debian GNU/Linux:
  Defaults write NSGlobalDomain NGBundlePath /usr/lib/opengroupware.org/Library/OpenGroupware.org
On RPM based distributions:
  Defaults write NSGlobalDomain NGBundlePath /opt/opengroupware.org/Library/OpenGroupware.org
